Fuel injection system for internal combustion engines has a fuel injection valve and a valve body with holes to spray out a cone-shaped injection jet

摘要

A fuel injection valve (4) injects fuel into a combustion chamber (7) with a spark plug (3) protruding into the combustion chamber and has a valve body (10) with multiple spray-out holes (11) designed so that a cone-shaped injection jet (5) is generated in the combustion chamber. The spray-out holes have a polygonal cross section.
